The beautiful supermodel is paying Diana Ross $500,000 to perform at her billionaire boyfriend, Vladimir Doronin's 50th birthday party, which will be taking place in Jodhpur, India.

DAYUM!!

A source revealed:

“Naomi is flying a lot of people out to India and paying for everything. No expense has been spared. Naomi’s team is even helping their friends secure visas. It will be the party of the century.”

The affair will be four days long and starts on Sunday, and not only is Ross getting generously PAID, but she will also be flown out in a private jet.

Reports also state that Naomi has booked a superb five-star resort and one of the functions will take place at the super fancy Umaid Bhawan Palace. And on top of that, she used the luxurious services of the Parisian travel expert, Omar Cherif, who owns OC Travel.

Sounds like Miz Campbell is paying back her beau for her spaceship mansion, because this PAR-TAY sounds like it's going to be off-the-hook!!
